Which solar heating system offers the best value?

The most logical way to calculate value is to look at cost per unit of energy rather than peak efficiency. The reasoning being that although a collector may be 15% more efficient than its competitor, if it is also 25% more expensive, then the competitions collector may be a better selection, as the cost of kWh of energy produced per day is cheaper.
